Open url and supply 2 fixed text fields

[swiimboy 0]

Hi. I use Alfred a lot but at no great level or depth.  I've created a hotkey to a new bank account and the site then wants 2 text fields which identify me but are not really part of the main security.   I am able to launch the URL successfully, but I would like to pre-fill those 2  irritating boxes. I've searched here, but found nothing which helps. Suggestions will be welcome.
